Build a Face Detection App in Python (OpenCV)

1 - Install OpenCV Libraries: pip install opencv-python
2 - Create a new file
3 - Write the code:

import cv2

face_cascade = cv2.CascadeClassifier('venv/Lib/site-packages/cv2/data/haarcascade_frontalface_default.xml')

eye_cascade = cv2.CascadeClassifier('venv/Lib/site-packages/cv2/data/haarcascade_eye.xml')

img = cv2.imread('images/face3.jpg')

gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

faces = face_cascade.detectMultiScale(gray, 1.3, 5)

for (x, y, w, h) in faces:

    img = cv2.rectangle(img, (x, y), (x + w, y + h), (255, 0, 0), 2)
    roi_gray = gray[y:y + h, x:x + w]
    roi_color = img[y:y + h, x:x + w]

    eyes = eye_cascade.detectMultiScale(roi_gray)

    for (ex, ey, ew, eh) in eyes:

        cv2.rectangle(roi_color, (ex, ey), (ex + ew, ey + eh), (0, 255, 0), 2)

cv2.imshow('img', img)

  1. can you make for indentify current face while using camera

  2. I haven't started to investigate the genuine degree of AI in this article, however perhaps I've aroused your advantage. artificial intelligence course

  3. i have this problem when run code
    C:\Users\user\PycharmProjects\Face_Recognition\venv\Scripts\python.exe C:/Users/user/PycharmProjects/Face_Recognition/
    Traceback (most recent call last):
    File "C:/Users/user/PycharmProjects/Face_Recognition/", line 16, in

  4. The content that I normally go through nowadays is not at all in parallel to what you have written. It has concurrently raised many questions that most readers have not yet considered.
